M-26: [D] [Debug] ini flags mirroring GE_PCDUMP / GE_INPUTLOG

- config.c: Debug.FrameDump (string) + Debug.InputLog (int).
  configGetFrameDump()/configGetInputLog() check the env var first
  (tools_pc/*.sh unaffected), fall back to the ini.
- video.c / input.c consumers switched to the accessors.
- GE_DETERM is design-only (D117), not mirrored.
- Verified: ini-only FrameDump=40-120:20 -> exactly 5 frames; GE_PCDUMP
  still overrides; -level_09 crash-free.
